Bigmaxximum
 

Hey Mike, do you think that the BK controllers can handle the big maxximum. I am facing the delima of either upgrading my Bl setup or going with the JT hybrid chassis with a rody C5.

The big Maximum is a 4 pole motor. I am not sure how the controllers will react for sure. In theory, it cuts the total rpm capability in half (on any controller vs a 2 pole motor). I used to have a JT hybrid. I like the e-maxx a lot better! Either of the "L" Feigaos or Lehner xl motors will produce plenty of power though. The 4 pole motors are very smooth, but also very expensive. I am a dealer for Plettenberg as well, so let me know if you want the maximum and I will see about getting it for you.

Well I guess I will just have to upgrade my brushless motor. I was thinking of getting a buggy anyways. As far as the Big maxximum goes what controller do you think can handle it reliably? I seen quite a few peoples schulze controllers going up in smoke.

I am getting some new controllers in next week or so. I will give them a run. I guess I will have to order a few pletty motors to test them. I will also ask BK if they have tried these motors with their controllers.

Thanks Mike. If you do get new pletty motors I will definitely be interested if the controllers can handle it.

I heard from a guy in Germany, that he was not able to run his bigmaxx on his BK 30/150 controller. It would simply not run powerfull enough.., nor rotate fast enough, or with terrible hiccups.. He tried to program his and play with the timing, but none of this worked..

The BK's top on a 4-pole is 50.000 rpm. With the bigmaxx on 16 cells, you allmost hit the 44000 rpm.. (i don't know if that 50K rpm is his material limit, his software limit or limited by his own frequency.

I also read and that there is a new type of 9918, which runs on a higher frequency.. (the one you can buy now, will be the new type)

I don’t know or heard about anyone running a esc, other then schulze, on his maximum/bigmaximum..

Personally I’m running my bigmaxximum on a schulze 18.97, and i smoked one 18.97... Now I’m running it with a mechanical brake, to spare the esc from the stress of the braking..

I know Plettenberg recommends the Schultze controllers, but that could be politics. Technically, the 4 pole motors ask twice as much of the speed controllers (hence the rpm limit is cut in half). The Schultze has a max rpm limit of 64000 on 4 pole motors if I remeber correctly. I will try the MGM controllers on the pletts also (see how well it works). These are some of the reasons I haven't stocked the Plettenberg motors. The motors themselves are very expensive and they need expensive controller to run them. Schultze also has a knack for not accepting a lot of responsibility for their controllers failure (I have blown a few for no apparent reason and had to pay for repair) This is kind of counter to my business startegy (competitive price with high value, backed by strong customer service). Never the less, I am curious, so I will try them. I know the Pletts are good motors, but a system could cost well into the $500+ range, which is twice what my average customer spends on a brushless setup.

I have read alot of horror stories with schulze and I personally dont want to deal with them. I have seen the Big Maxx perform and am curious to see what 1800 watts can do.

I also plan to build up a buggy here soon and am debating whether to do a e conversion or stick a rody c5 in it.

I am sure lipomaxx ans serum may step in here with some experience, but the rated wattage of a motor is somewhat misleading. I know lipomaxx has a data recording system and has pulled upwards of 1000watts at near 100 amps from the little basic 2700 motor (rated for 700 wats and 35 amps). I am sure the big maximum is powerful, but the most likely factor to limit performance will be the batteries (ability to deliver the power), not the motor. I am sure a basic xl (rated for 1300 watts) or any of the Feigaos I carry could put out upwards of 2000 watts for short periods of time. Unless you plan on towing yourself around, you don't need this much power continuously.

I can drop in my 7XL as soon as i have got it.

I am very curious about the difference between those two..

We are waiting for the Truggies to come in off back order. Hopefully next week!

Any word on the pinions we spoke about?

You mean the HB?

Nice.......

Very nice..

In my opinion a unbeatable combo..

Sell the nitro setup, build it brushless.. You've got a cheap but superb brushless car then.. (doesn't need expensive drivetrain upgrades)

Yes. The HB Lightnong Pro stadium truck, converted to brushless power! Should be an animal on the track!

Yes!

I'm expecting them this week (i guess they will come mondey/tuesday (it's sunday now))

Can you email me your address?
